In Dewsnup v. Timm, 502 U.S. 410, 417-20, 112 S.Ct. 773, 778-80, 116 L.Ed.2d 903 (1992), the Court gave the term "allowed secured claim" a different meaning in two subsections of the same bankruptcy provision, based on a difference in context and a reluctance to infer that Congress had altered a settled rule of pre-Code bankruptcy law. In the case of Foreign Affairs Manual ("FAM") 628.2, the uncertainty over the government's constitutional power to authorize punishment for publication of material disapproved by the agency, together with the obscurities produced by interpreting the regulation to authorize such punishment, provide a basis for adopting differing interpretations of "cleared" and "clearance" in 628.2b and 628.2c.
